I followed your advice and changed the post to draft, failed still but this time on a different post.
When I disabled that second post, the process was completed!

These are all licensed or free from the WP repository.
So I changed those to posts back to published and tried crawling again while disabling plugins one by one.
Any individual plugin deactivated from the above list if my posts were published and not draft, the crawl failed.
So I switched the theme to the standard WordPress theme with those posts published,
the crawl was successful!
So it looks like the theme is doing something to cause your crawl to fail on only the posts.
